I'm having a tough time getting out what should be easy. I have an old colt AR that I wanted to snug up the barrel nut on. The barrel can be move a little by rotating it. Which then can throw off the front sight. Its just open sights standard M4 A2 front sight and old fashion carrying handle.
Rather than remove the entire sight I though just punch out the pin holding the gas tube to the front sight. Easy right? Wrong.
Unlike most A2 sights this one did not have the pin flush on both sides more like counter sunk 1/8" or so. So using 3 different 1/16" punches one starret and two other roll pin punches I tried to punch it out. Just ended up with 3 bent punches. Used oil lube etc. I'm almost thinking there was never a pin in there and like someone put a gas tube in without that drilled hole that the pin goes through to secure it. Is this possible? I can't pull it out so something is holding it.
Its not a new gun its probably 30 years old. It works fine except for barrel being a little loose, if you grab the barrel you can twist it side to side stopped by the front barrel pin. Which to me means that snugging up the barrel nut might be all it needs.
Can this be hand drilled out and just put a new roll pin in?
Or I guess I could take the entire front sight off which might not be that easy either.
